A simple but genius mod. As you can see mine did not print great due to a giant mess (clog) in my hot end, but it was functional. Once printed I disassembled and cleaned out the filament blob from the factory Creality setup (gap). Installed this mod to eliminate gap and was immediately back to printing. So far my extrusion is much more consistent and I’m not seeing random blobs in my walls anymore. I for sure needed this for my Ender 5.
